BD9B333GWZ-E2 is a synchronous buck DC/DC converter with built-in low on-resistance power MOSFETs. This IC, which is capable of providing current up to 3A, features fast transient response by employing constant on-time control system. It offers high oscillating frequency at low inductance. With its original constant on-time control method which operates low consumption at light load, this product is ideal for equipment and devices that demand minimal standby power consumption. BD9B333GWZ-E2 achieves the high power density and offer a small footprint on the PCB by employing small CSP package.
